创建一个在文本中查找大写单词的映射器

Question

Implement filescounter, which takes a string in any variety and returns the number of capitalized words in that string, inclusive of the last and first character.

def filescounter(s):
    sr=0
    for words in text:
        #...
    return sr

I'm stuck on how to go about this.

Answer 1

Split the text on whitespace then iterate through the words:

def countCapitalized(text):
    count = 0
    for word in text.split():
        if word.isupper():
            count += 1
    return count

If, by capitalized, you mean only the first letter needs to be capitalized, then you can replace word.isupper() with word[0].isupper() .

Answer 2

Use this:

def count_upper_words(text):
    return sum(1 for word in text.split() if word.isupper())

Explanation:

• split() chops text to words by either spaces or newlines
• so called list comprehension works faster than an explicit for-loop and looks nicer
